"The NeedakŪ Soft-Bounce™ rebounder is the same high quality NeedakŪ rebounder that J.B. Berns recommends for gym use."
-Urban Rebounding by J.B. Berns
"The NeedakŪ Soft-bounce™ IS the standard of rebounders! Well made, comfortable and practically indestructible it is the only rebounder I recommend in my books' exercise sections."

"Most important for excellent rebounding is the mat material. It should give no stretch during the downward landing, while at the same time providing a resilient rebound. Such a mat will be made from Permatron material, which has a smooth finish. The Permatron is resistant to ultraviolet rays, doesn't break down as do other fabrics, and allows no moisture absorption. Part of the specifications for a perfect rebounder is that its mat will be sewn together using 5760 stitches of high-grade nylon thread with two layers of strong polypropylene webbing stitched around the mat's edges.
Attached to a heavy-grade, all steel round frame should be an oversize spring mechanism holding four-inch-long, custom-made jumbo springs which deliver a soft bounce. Thirty-six springs made of quality wire will hold the mat to the frame. The springs should be shielded by a protective cover. Individual spring mounting pins prevent frame wear. Tapered coils help to give extended wearability to such springs. (Untapered coils allow low-quality springs to break frequently, requiring replacement.) Replacement springs must be available directly from the manufacturer since retail distributors seldom stock spare springs.
The spring-loaded legs should fold for easy storage under a bed or behind a door. For a folding rebounder, the frame should fold in half to be packed into its carrying bag, allowing for storage in a car trunk.
To jump for health, rebounding devices that exhibit all of these features of excellence I've been describing are the NeedakŪ rebounders. They meet all of these specifications for the ideal rebounding device."
